STA015
BASS_ENHANCE
Address: 0x7C (1240
Software Reset: 0x00
Hardware Reset: 0x00
Signed number (2 complement)
This register is used to select the enhancement or attenuation STA015 has to perform on Bass Frequency
range at the digital signal. A decrement (increment) of a decimal unit corresponds to a step of attenuation
(enhancement) of 1.5dB.
The allowed Attenuation/Enhancement range is [-18dB, +18dB].
TONE_ATTEN
Address: 0x7D (125)
Type: RW
Software Reset: 0x00
Hardware Reset: 0x00
In the digital output audio, the full signal is achieved with 0 dB of attenuation. For this reason, before ap-
plying Bass & Treble Control, the user has to set the TONE_ATTEN register to the maximum value of en-
38/56
